Simple Solutions for Fixing NET::ERR_CERT_AUTHORITY_INVALID

NET::ERR_CERT_AUTHORITY_INVALID is encountered when the browser is unable to certify the Secured Sockets Layer (SSL) of the given website, or it is seen as INVALID. It implies net is uncertain that the SSL certification was issued by CA whose reliability of the browser question, increases the probability of being in a dangerous connection.

SSL certificates are one of the primary advantages of data transfer security. The NET: ERR_CERT_AUTHORITY_INVALID error could potentially harm online traffic, especially search engine optimization (SEO) rankings. To promote continued user confidence and ensure the website’s validity, administrators must take immediate steps to correct this problem.

Several tested fixes for the net::err_cert_authority_invalid error message are covered in this article. Let’s investigate its common causes first.

The Meaning of the Error Code NET::ERR_CERT_AUTHORITY_INVALID

Browsers that might be unable to check SSL certificates for a website may also display the security-related message NET::ERR_CERT_AUTHORITY_INVALID. If users proceed despite this warning, they might mistakenly assume that the website obtained its SSL certificate from an unreliable Certificate Authority (CA), potentially exposing user data and critical information. While unsecured network connections, browser caches, and expired SSL certificates are commonly implicated, we cannot deny that they are among the most notorious culprits.


NET::ERR_CERT_AUTHORITY_ is the following SSL and browser-related problems that may cause an INVALID error:

  • Expired SSL certificates: Until the certificate is renewed, a browser will typically flag an expired certificate as invalid.
  • Self-signed certificates: These SSL certificates do not have the third-party verification browsers authorities need and are not prepared by a Certificate Authority (CA).
  • Inaccurate time and date: An outdated operation system may have a most dependable and precise time and date setting, under which it might simply treat a valid certificate as faulty only because it has expired.
  • Untrusted Certificate Authority: The SSL certificate for your website was obtained from an unidentified CA that isn’t included in the trusted certification authority list for browsers.
  • SSL state or outdated browser cache: For quicker connections, browsers save cached certificates, however, a corrupted or outdated cache might cause a discrepancy with the real certificate.
  • Interference from virtual private networks VPNs: Certain security programs, such as firewalls and antivirus software, can cause problems with the SSL handshake procedure and cause browser warnings.
  • Conflicting browser extensions: When a browser tries to check certificate information, an extension may mistakenly alter or prevent it.

How Various Browsers Display the NET::ERR_CERT_AUTHORITY_INVALID Error

Different browsers show visitors the problem as the ERR_CERT_AUTHORITY_INVALID in various ways. Let’s use them as “benchmarks” for the Edge Browser, Mozilla Firefox, Google Chrome, and Apple Safari.

This specific problem can be caused by several different things, but it is entirely fixable. Starting with the simplest, we’ll guide you through the fixes for the NET::ERR_CERT_AUTHORITY_INVALID problem.

Modify Your Computer’s Time and Date Settings

External factors like daylight saving time, battery issues, or incorrect time zone settings on a system can modify time settings. The expiration of a valid SSL certificate by the browser may occur when the date is incorrect or the time is not entered properly.

On Windows devices, use these steps to change the date and time again:

  1. Switch to the Date & time settings menu by opening the Start menu.
  2. Click Sync now from the Additional Settings section.
  3. To maintain the accuracy of your device’s time, especially when traveling, turn on the Set time zone automatically option.

If you’re using macOS, do the following:

  2. Navigate to System Preferences → General → Time & Date.
  3. Turn on the option to Set a date & time automatically.
  4. Verify that you are using the right time zone by going to Time Zone.

Check to see if the problem goes away by refreshing the browser after adjusting the time and date on your operating system.

Upgrade your web browser

Older browsers might cause problems such as the NET::ERR_CERT_AUTHORITY_INVALID error since security protocols evolve fast, as technologies develop, and operators do not always update their networks in time. In the means, you should resolve the issue by updating the version of your browser.

To check for and update Google Chrome, take the following actions:

  1. Reach the menu with three dots in the upper right corner and choose Settings -> About Chrome.
  2. A notification stating that Chrome is up to date will appear if your browser is current.
  3. Should there be a Google Chrome update, the Update Google Chrome button will show up. After clicking it to begin the update download, choose Relaunch to finish the procedure.

Turn Off Browser Extensions for a While

The usability and usefulness of online browsing are improved by browser extensions. Some of them, however, can alter how browsers load content, which might result in SSL issues.

If browser extensions are the source of the NET::ERR_CERT_AUTHORITY_INVALID issue, they may be disabled.

The procedure for deactivating browser extensions is the same across widely used browsers. This is the procedure on Google Chrome:

  1. Choose Extensions → Manage Extensions from the three dots menu located at the top right of the screen.
  2. Turn off every extension that is currently in use.
  3. Try reloading the website to see if the problem still exists. If this fixes the problem, go ahead and activate each extension individually to find the offending one.

Clear the Cache and Cookies in Your Browser

Browsers can accelerate page display by gradually receiving cookies and reusing data that has been modified. On the other hand, the slippage from outdated or erroneous files is an emerging issue of SSLs since the information is not authentic.

Once you apply these tips, if you can see the website while you are in incognito mode, you know both the browser cache may have expired or the web browser could be the cause of the problem itself. If after all this, you are still not able to get things about the browser cache to work for you like it is intended, you must clear it.

Popular browsers all use a similar procedure for cache clearing. Here’s how to delete cookies and cache from Google Chrome:

  1. To clear browsing data, click the three dots menu located in the upper right corner.
  2. After choosing the time frame, make sure to remove every piece. To get rid of the files your browser has cached, click Clear data.

Turn off your VPN.

To encrypt the link, and keep an IP address private in an internet virtual private network would make internet privacy and security much better thus, one can access geo-restricted material and browse safely.

Nevertheless, routing techniques or security protocols may cause it to interfere with SSL certificate validation, resulting in the NET: My computer is unable to securely verify the website due to the ERR_CERT_AUTHORITY_INVALID error message.

If deactivating the VPN does not resolve the issue, try to plug in the router in a different power outlet. If the issue is resolved, consider using another VPN or speak with the VPN’s support staff.

Delete the SSL State

SSL and browser cache are responsible for saving data related to secure connections, such as web page data and passwords entered on specific websites. Your computer may occasionally save inaccurate or out-of-date SSL certificate data from websites you visit, which might result in the NET: ERROR_CERT_AUTHORITY_INVALID error. These certification credential overrides are removed by deleting the SSL state.

To clear the SSL status on Windows, follow these steps:

  1. To find Internet Options, open the Start menu and type its name.
  2. Navigate to the Content tab in the Internet Options section.
  3. Select Clear SSL State.

Take the following actions on macOS to remove any unrecognized certificates:

  1. To find Keychain Access, click the Spotlight search button at the top of the screen.
  2. Choose Certificates from the System category.
  3. Look for certificates with a red “X” icon indicating they are untrustworthy.
  4. Select Delete with a right-click on the certificate that is causing issues.

Disable your antivirus or firewall

Let’s try to look at your system security by shutting down your firewall or antivirus program if all other methods of contact fail. Their security protocols may occasionally cause issues with the validation of SSL certificates, which might result in the NET: SSL_CERT_UNKNOWN_ISSUER or ERR_CERT_AUTHORITY_INVALID.

To disable Windows Firewall, take these steps:

  1. From the Start menu, select the Control Panel.
  2. Go to Windows Defender Firewall under System and Security.
  3. On the sidebar, choose Turn Windows Defender Firewall On or Off.
  4. For both private and public network settings, choose Turn off Windows Defender Firewall (not recommended).

Here’s how to disable macOS’s firewall:

  1. Launch the Apple menu.
  2. Navigate to System Preferences → Network.
  3. To turn off the function, go to the Firewall section and toggle it off.

The method varies depending on whether the program turns off the antivirus. Search for the wheelchair software’s options to disable the software temporarily, or refer to the help files provided by the program.

See how the page works after disabling your browser protection options by going to your browser settings menu and clearing them. To find the source of the NET: If the system is connected to the Internet, it is worth running diagnostics through antivirus programs and firewalls.

If it’s one of them, you can take the following actions:

  • Permit the website to pass past your antivirus or firewall settings.
  • For assistance, get in touch with your antivirus support staff.
  • Search for substitute antivirus or firewall programs.

Update the SSL certificate

During issuance, an issuer allows the largest period of validity for an SSL certificate, which is 13 months or 398 days, although this varies by issuer. Updating an SSL certificate does not affect the security of your website, which it maintains.

It is advised that the SSL certificate may be manually reissued at least 30 days before its expiration date for automatic renewal of the paid certificate only, in case it is free.

To check the certificate’s expiration date on Google Chrome, take the following actions:

  1. Click the padlock or View site information button in the address bar.
  2. Choose “Select Connection is Secure → Valid Certificate.” The information on the website’s certificate, including its validity duration, will be shown in a new window.

If your SSL certificate has expired you have to contact the provider to receive information regarding the renewing of your key. Acquiring a new certificate, creating a CSR or a non-standard certificate that matches with private data, and, finally, installing the certificate on the web server are the processes that finally launch the process.

Execute an SSL Verification
